Plug-in hybrids are not only (potentially) very economical, they often also have a lot of power. Which plug hybrid combines these two virtues best? We test the BMW X3 xDrive30e, Volvo XC60 Recharge T6 AWD, Hyundai Santa Fe 1.6 T-GDI PHEV 4WD and Land Rover Discovery Sport P300e. In this partial test we focus on the plug-in hybrid powertrain.
Earlier we concluded that the comfort of these plug-in SUVs was at a high level. That is of course also possible in this price range. The Hyundai Santa Fe is the cheapest in the list, but still has a starting price of 53,945 euros. The other three all start on the ‘wrong’ side of the 60,000 euros. In the tested version, the luxurious Volvo XC60 takes the cake. Certainly if you consciously opt for a plug-in hybrid powertrain, you expect a lot from the performance and consumption. In this sub-test we therefore emphasize the combination of engine and transmission.
Different types of plug-in hybrids
The principle of the plug-in hybrid is approached here in two different ways. BMW and Hyundai put the electric motor between the petrol engine and the transmission. They then distribute the electrical power simultaneously with the fossil power to all four wheels. Land Rover and Volvo keep both engines strictly separate. In the case of the Land Rover Discovery Sport, a three-cylinder 1.5-litre turbo engine along with an eight-speed automatic transmission drives the front wheels. The electric motor is housed in the rear axle, without mechanical connection to the petrol engine in the front.

Volvo XC60 Recharge T6 crushes competition with its performance
Volvo relies on a powerful four-cylinder with a capacity of two liters. That engine not only has a turbo, but also a mechanical compressor. Volvo has significantly boosted the power: on top of the 253 hp that the four-cylinder transfers to the front wheels, the rear wheels also receive 145 hp of electrical power. No wonder the XC60 Recharge T6 crushes its competitors in the performance measurements.
It sprints from 0 to 100 km/h in 5.3 seconds, the BMW follows in 5.9 seconds and the Land Rover in 6.8 seconds. The Hyundai splits the rows with a hundred sprint in 8 seconds. The Volvo XC60 is therefore unstoppable. At least: up to 180 km/h. Because Volvo has electronically determined that it is better for road safety not to go faster. Even the Hyundai Santa Fe makes good ground on the Volvo with its modest top speed of 187 km/h.
350 hp of the Volvo XC60 difficult to dose
The energetic power of the XC60 is difficult to dose. The Land Rover Discovery Sport and the BMW X3 transfer their forces to the wheels much more evenly. When the petrol engines of the Volvo and the Hyundai take over from the electric motors, it is also accompanied by a lot of fanfare. In the BMW X3 xDrive30e you rarely realize which engine is working. This is only the case with the three-cylinder Land Rover if you don’t ask too much of it. As long as you stay away from the rev limiter, it stays neatly in the background.
Payload plug-in hybrids
By the way, the Land Rover Discovery Sport P300e is the only car in this test that can be charged with a power of up to 7 kW. The batteries of the three other plug-in hybrids drip with a maximum of 3.7 kW (BMW X3, VolvoXC60) to 4.6 kW (Hyundai Sana Fe) full. In addition, the Land Rover can be charged on a fast charger with a capacity of 32 kW.
How economical are plug-in hybrids really?
When we compare the consumption measurements of the BMW X3 xDrive30e, Volvo XC60 Recharge T6 AWD, Hyundai Santa Fe 1.6 T-GDI PHEV 4WD and Land Rover Discovery Sport P300e against the manufacturer’s specifications, we are able to send an angry letter to the editors of Kassa. send. The Hyundai Santa Fe achieves an average test consumption of 6.3 l/100 km (1 in 15.9), the Land Rover Discovery Sport does not go further than 7.6 l/100 km (1 in 13.2). A huge difference with the 1.5 liters that the British give up (1 in 66.7). Both the BMW X3 and the Volvo XC60 noted a consumption of 1 to 14.7 during the test.
This is how we test the consumption of plug-in hybrids
In order to assess the consumption figures mentioned above, we think it is important that you know how we measure them. We have a fixed test route of more than 100 kilometers in which city traffic, provincial roads and highways alternate. We drive this route twice. First with a fully charged hybrid battery and a second time with an empty battery.
If you dutifully roll out the charging cable and charge the batteries every day, you can drive fully electrically over a realistic distance of 37 (BMW) to 49 kilometers (Hyundai). In South Korea, economy is apparently higher on the list than pure speed – and that is certainly no shame. Depending on the conditions of use, the fuel consumption of plug-in hybrids can therefore vary greatly. Much more than with cars with a traditional powertrain.
And the winner is …
If we summarize our findings, the BMW X3 xDrive30e offers the best compromise of performance, consumption and inner civilization. The Volvo delivers the most impressive performance. The Land Rover Discovery Sport P300e is less fast than the BMW and Volvo and consumes the most, but again has a fine working transmission. Although the Hyundai Santa Fe PHEV is clearly less fast than the rest, its powertrain is the most restless. The Korean puts the best consumption figures on the positive side of the scales.
